CPU Preformance Degraded

Okay so I upgraded my old cpu from a ryzen 3 1200 to a ryzen 7 2700. When I installed it, everything had looked fine, but whenever I tried playing my games they would just crash out of no where. I figured that this might be the power supply so I upgraded my EVGA 450 watt bronze to a 750 watt Gold plus. That fixed the issue but then I ran cinebench. My score was anywhere from 800 to 900. While before I replaced the power supply, my score was 1,500. I don't know what the hell happened. Maybe I screwed something up while I was setting up my psu since this is my first time I've done something like this. Does anyone have any idea of what it could be?

Specs:
gpu: GTX 1060 3gb
cpu: Ryzen 7 1700
Motherboard: B350 Gaming Pro
ram: Corsair vengeance 8gb
Power supply: EVGA 750 GQ

Are you monitoring temps? It's possible you may have bumed cpu cooler loose. Sounds like your cpu may be thermal throttling. Potentially causing your low scores

How would I be able to check this? I tried using AIDA64 but that it only checks for thermal throttling on intels chips. I also don't see a way that I might have done anything to the cooler since it is on there pretty tight. I don't see how I might have bumped it loose. Also I have msi afterburner on when I play games and the usual temps are around 50 to 55 Celsius. I've been running the AIDA64 stability test for like 7 minutes and my screen froze twice for like 2 or 3 seconds. Idk if this is a sign of thermal throttling or not since my max temp so far is 65 Celsius.

Update: I've been running the AIDA64 stability test for 5 minutes and I saw my screen freeze up for about 2 or 3 seconds like twice. I just finished it for 20 minutes and never went up 66 Celsius.
